3 Claims. CL 30-124) This invention relates to an attachment for a tool, and more specifically, to a guard for wire cutting devices.

Radio and electrical workers are constantly faced with the possibility of incurring an injury to the eye when trimming a wire lead with wire snipping or cutting devices. it is impossible to gauge with accuracy exactly where the severed end may go and since it leaves the tool at considerable speed and force, physical injury may attend the operator of the tool or individuals proximate to him, the injury generally being to the eye. Consequently, one of the primary objects of this invention is to provide in combination with a wire cutting device, means for protecting the operator thereof and persons adjacent him from physical harm caused by the sudden propulsion through the air of a severed piece of trimmed wire.

Another object of this invention is to provide a guard for a tool of the type described which is adapted to collect therein the severed trimmed ends of wire.

A further object of this invention is to provide a guard for a wire cutting tool which is inexpensive to manufacture, non-complex in operation and assembly, and durable in use.

Other and further objects and advantages of this invention will become more apparent from a consideration of the following specification when read in conjunction with the annexed drawing, in which:

Figure 1 is a top plan view of a tool attachment constructed in accordance with the teachings of this invention.

Figure 2 is a fragmentary cross-sectional view taken on the horizontal plane of line 22 of Figure 1, looking in the direction of the arrows.

Figure 3 is an end elevational view of the tool and the attachment illustrated in Figure 1.

Figure 4 is an exploded view of the attachment.

Referring now more specifically to the drawing, reference numeral designates, in general, a wire cutter having secured thereto an attachment comprising a guard and constructed in accordance with the teachings of this invention. As seen in the drawing, the tool 10 is formed of a pair of elongated members 12, 14 which are pivoted on a pivot pin 16 disposed adjacent one of their respective ends. The members 12, 14 are crossed at their pivoted ends and are provided with cutting edges 18, 20 adjacent one of their respective ends.

The guard 30, to which this invention relates, comprises an elongated substantially U-shaped member 32 having upwardly extending side walls 34, 36, and an end wall 38. The side walls 34, 36 and the end wall 38 are provided with laterally and outwardly extending flanges 40, 42 and 44, respectively.

A substantially U-shaped clamp plate 46 is disposed on one side of the end wall 38 and is positioned within the guard 30. The end wall 38 is tightly clamped between clamp plate 46 and an arm 48 of an L-shaped bracket 50 able apertures 54, 56 and 58 formed in the clamp plate 46, the end wall 38, and the arm 48 of bracket 50, respectively.

As is seen in the drawing, flange 44 overlies the other arm 60 of the bracket and is disposed substantially adjacent the pin 16.

The guard 30 is secured to the underside of the lowermost member 12 with the flange 44 and the extended portion of the arm 60 engaging thereagainst as is illustrated in Figure 2. The arm 60 is fixedly mounted on the member 12 by any conventional means such as, for example, smelting, or welding, or soldering.

The guard 30 may be formed of any desired material such as of a transparent plastic or metal and may be made as an integral unit if found desirable.

With the guard attachment positioned as shown in Figures 1, 2 and 3 of the drawing, any small piece or pieces of wire which may be cut by the tool are adapted to fall in and be received by the guard 30. Under such usage, the wire chips are prevented from falling on or into the equipment immediately adjacent to the wire being severed and also provides a means for collecting stray wire bits for salvage.

By inverting the tool from the position shown in Figure 2, the guard 30 will effectively prevent wire chips or pieces from being propelled through the air for impingement against personnel to their physical damage.

Having described and illustrated one embodiment of this invention in detail, it will be understood that the same is offered merely by way of example, and that the invention is to be limited only by the scope of the appended claims.

What is claimed is:

1. A guard for a wire cutting tool having a pair of cutting blades at one end thereof, said guard comprising a pair of spaced side walls and an integrally formed bottom wall, an integrally formed closure wall for one end of said guard, said closure wall having a laterally extending flange, and bracket means for securing said flange and said closure wall to said tool adjacent its said cutting end.

2. A guard for a wire cutting tool having cutting blades at one end thereof, said guard comprising a substantially U-shaped channel member having a closure wall at one end thereof, said closure wall having a laterally extending flange integrally formed therewith, a L-shaped bracket having one of its arms engaged against said closure wall and the other of its arms engaging against said flange, means for securing said first arm to said closure wall, and means securing the said other arm of said bracket to said tool to subtend said guard immediately below the cutting end of said tool.

3. A guard for a wire cutting tool comprising a substantially U-shaped channel member having an integrally formed closure wall at one end thereof, said closure wall having an integrally formed laterally extending flange, a brace plate disposed within said guard in juxtaposition with respect to said closure wall, an L-shaped bracket member having one of its arms engaging against said closure wall, said bracket having the other arm thereof engaging against said fiange, means extending through and securing said one arm, said closure wall, and said brace plate, and means for securing the other of said arms to said tool with said guard positioned immediately adjacent a said cutting end thereof.
